What else can I help you with?
Where do the axons and dendrites meet?
Axons and dendrites meet at the synapse, which is the junction between two neurons. The axon terminal of one neuron releases neurotransmitters that bind to receptors on the dendrites of the adjacent neuron, facilitating communication between the two cells. This connection is crucial for transmitting signals throughout the nervous system.
What are the two kinds of branches that extend from the cell body of a neuron?
The two kinds of branches that extend from the cell body of a neuron are dendrites and axons. Dendrites receive signals from other neurons and transmit them towards the cell body, while axons transmit signals away from the cell body to other neurons or target cells.
What is the spce between two neurons where the axon of a sending neuron communicates with the dendrites of a receiving neuron by using chemical messages called?
The space between two neurons where communication occurs using chemical messages is called the synaptic cleft. Neurotransmitters are released from the axon terminal of the sending neuron and bind to receptors on the dendrites of the receiving neuron, facilitating the transmission of signals between the two.
What are the two kinds of branches that extend from the cell body of a neuron what does each do?
The ones carrying the input are the dendrites, the ones carrying the output are the axons.
The two poles in a neuron?
A neuron typically has two main poles: the axon and the dendrites. Dendrites receive incoming signals from other neurons, while the axon transmits electrical impulses away from the cell body to communicate with other neurons or target cells. This bipolar structure allows for the efficient processing and transmission of information within the nervous system.
What happens at the synapse between two neuron?
At the synapse, the electrical impulse between the two neutrons at synapse set of chain chemical reactions which create a chemical impulse at the synapse.
What are the two parts the neuron is split up into?
There are actually 3 parts to a neuron. The dendrites are tree branch like projections that receive nerve impulses from another neuron, the cell body that contains the nucleus, and the axon, a long fiber that carries the nerve impulse away from the cell body to the next neuron.
What do we call it when contrast between two poles of a neuron?
The contrast between two poles of a neuron is typically referred to as the "polarization" of the neuron. This involves the difference in charge between the inside and outside of the neuron's membrane, which is crucial for the generation and propagation of action potentials. The two poles are commonly described as the axon (which conducts impulses away from the cell body) and the dendrites (which receive signals). This polarization is essential for the neuron's ability to transmit electrical signals efficiently.
What is the junction between the axon and the dendrites?
The junction between the axon of one neuron and the dendrites of another neuron is called a synapse. This is where communication occurs between neurons through the release and reception of neurotransmitters. The synapse is a crucial point for signal transmission in the nervous system.
The most type of neuron in the human body is?
Multipolar neurons This is the most common type of neuron, with one axon and many dendrites. Multipolar neurons are so-named because they have many (multi-) processes that extend from the cell body: lots of dendrites plus a single axon. Functionally, these neurons are either motor (conducting impulses that will cause activity such as the contraction of muscles) or association (conducting impulses and permitting 'communication' between neurons within the central nervous system).
Use the analogy of a battery as having positive and negative poles the contrast between two poles of a neuron is called?
The contrast between the two poles of a neuron is called polarization. Just like a battery has positive and negative poles that create an electrical potential difference, a neuron's polarization refers to the difference in electric charge between its dendrites and axon. This difference in charge allows for the transmission of electrical impulses along the neuron.
What is a tiny branching thread-like structure found in neurons?
There are two possible answers - axons or dendrites. Axons carry action potentials away from the neuron, while dendrites receive action potentials.
